Abstract

To mitigate the damaging impacts caused by interference
and hidden terminals, it has proposed to use orthogonal
channels in multi-hop wireless mesh networks. We demonstrate
however that even if these issues are completely eliminated
with perfectly assigned channels, gross unfairness can still exist amongst competing flows which traverse multiple hops. We propose the use of 802.lle's TXOP mechanism to restore/enforce fairness. The proposed scheme is simple, implementable using off-the-shelf devices and fully decentralised (requires no message passing).
